Answer:

2 Silver Ions

1 Oxygen Ion

Explanation:

Edg2021

The chemical symbol for silver oxide is not Ag₂0. The correct chemical formula for silver oxide is Ag₂O.

Silver oxide (Ag₂O) is an ionic compound composed of silver ions (Ag⁺) and oxide ions (O₂⁻). It is commonly used in button batteries as a cathode material. In this compound, two silver ions combine with one oxide ion to form a stable structure.

The chemical formula Ag₂O indicates that there are two silver ions (Ag⁺) and one oxide ion (O₂⁻) in each formula unit of silver oxide. The subscript 2 after Ag indicates that there are two Ag⁺ ions present, while the absence of a subscript after O indicates that there is one O₂⁻ ion.

Hence, the chemical formulae are discussed above.

Explanation:

55 kilometers per hour to meters per second

First we have to convert the kilometers to grams;

1 kilometer = 1,000 meters

This means we have;

55000 meters per hour

Converting hour to seconds;

1 hour = 60 minutes

1 minute = 60 seconds

1 hour = 60 * 60 = 3600 seconds

We divide 55000 by 3600;

55000 / 3600 = 15.28 meters per second

B: it can be flattened and bent

Explanation:

Metals are malleable and can be flattened. Metals are ductile and can be deformed and bent.

Metals are bonded together by metallic bonds.

Hence a substance that is composed of atoms that are held together by metallic bonds can be flattened and bent.

The property of a substance that is composed of atoms that are held together by metallic bonds is  it can be flattened and bent

Metals are malleable, ductile substance can be deformed when it is bent down, theses are bonded by metallic bond and can be flattened.

The metallic bond is a force of attraction which is responsible for holding the atoms together,  releases electrons to achieve the configuration of a noble gas.

in this type of bonding all the atoms lose their electrons from their outermost layers that move more or less freely between them, forming an electronic cloud

The metallic bond is the exceptional bond where the electrons are not present exclusively between a pair of atoms, but these are relocated among millions of them  called as  "sea of ​​electrons"  by cohesive bond.

Answer:

The main cause of global convection currents is the uneven heating of the earth by the sun. Hope this helped! :)

The main cause of global convection current is differential heating, that is the temperature difference in different levels of  atmosphere.

Convection current  is the heat transfer by fluid movement in the earth crust between different temperature regions. The density of fluids differs due to the temperature gradients and thus heated fluids raises and cooled fluid sinks.

The heated fluid movement causes the movement of plates of earth. The molten rock deep inside the earth crust circulates by the convection current.

Hence, the main cause of global convection current is the differential heating of the atmosphere.

Answer:

D) freezing

Explanation:Because hail sounds like it is hard and hail comes down and it hurts because it is freezing.

The hail can be defined as the conversion of the water to the ice. Thus, hail is an example of freezing.

The phase can be defined as the state of the matter. With the change in the temperature and the pressure values, the state of the matter, or the phase changes.

The hail has been the solid precipitation of the rain water. With the lowering of the temperature to the critical pressure, the water converts to ice.

The conversion of water to ice has been termed as freezing, Thus, hail is an example of freezing. Hence, option D is correct.
